Hi
I´m relatve unexperienced using proc mixed.
My problem is, that running lsmeans in my reduced model results in the message Non-est. instead of an estimate.
Don´t understand why.
Can anyone help, please ??
Model:
Repeated measurement of the variable region at mri_id, wbvcalc as covariante.
Proc Mixed Data=kerstin1 method=ml covtest scoring=2;
Class mri_id sex0F1M region hemi agegroup ;
Model response = region sex0f1m hemi age WBVCalc
region * age
region * wbvcalc
/noint solution ;
repeated / Subject=mri_id type=cs group = region ;
lsmeans region / pdiff;
Run;
